Five years ago keeping track of Mac malware was an interesting hobby for security geeks. Examples popped up every now and then, security firms put out a press release, and everything went back to normal. There just wasn’t much to talk about. Then, in 2012, something called Flashback hit the platform, anything up to a million users were infected, and perceptions changed. Today’s Mac and iOS threats have stepped up a gear with three malware families appearing to target the Mac in 2016 alone. That sounds modest but many users are still under-protected.
